Why the Four Facet Split Point Makes a Difference
The four facet split point design on these carbide jobber drills is like having four tiny cutting edges meeting perfectly at the tip. Instead of scraping or wobbling on the surface, this point helps the drill bite into the material precisely, reducing walking and making your initial drilling easier and more accurate. Think of it as the difference between trying to start a hole with a blunt pencil versus a freshly sharpened one—the split point saves you effort and improves results every time.
